I have recently hit a problem that some of my Azure DevOps YAML pipelines, that I use to build my Azure DevOps Pipeline Extensions, are not triggering on a new PR being created on GitHub. I did not get to the bottom of why this is happening, but I found a fix. Check and of make a note of any UI declared variables in your Azure DevOps YAML Pipeline that is not triggering Delete the pipeline Re-add the pipeline, linking to the YAML file hosted on GitHub. You might be asked to re-authorise the link between Azure DevOps Pipelines and GitHub. Re-enter any variables that are declared via the Pipelines UI and save the changes Your pipeline should start to be triggered again ...

A common request for my Generate Release Notes Tasks is to enrich the data available beyond basic build, work item and commit/changeset details. I have resisted these requests as it felt like a never ending journey to start. However, I have now relented and added the option to see any pull request information available. This feature is limited, you obviously have to be using artifacts that linked to a Git repo, and also the Git repo have to on an Azure DevOps hosted repository. This won’t meet everyone’s needs but it is a start. ...

Background GitHub is a great system for individuals and OSS communities for both public and private project. However, corporate customers commonly want more control over their system than the standard GitHub offering. It is for this reason GitHub offers GitHub Enterprise. For most corporates, the essential feature that GitHub Enterprise offers is the use Single Sign On (SSO) i.e. allowing users to login to GitHub using their corporate directory accounts. I wanted to see how easy this was to setup when you are using Azure Active Directory (AAD). ...

I recently got a very interesting PR for my Cross-platform Release Notes Azure DevOps Pipelines Extension from Kenneth Scott. He had added a new templating engine to the task, Handlebars. Previous to this PR the templating in the task was done with a line by line evaluation of a template that used my own mark-up. This method worked but has limitations, mostly due to the line by line evaluation model. With the Kenneth’s PR the option was added to write your templates in Handlebars, or stay with my previous templating engine. ...

Problem I recently tripped myself up whist adding SonarQube analysis to a rather complex Azure DevOps build. The build has two VsTest steps, both were using the same folder for their test result files. When the first VsTest task ran it created the expected .TRX and .COVERAGE files and then published its results to Azure DevOps, but when the second VsTest task ran it over wrote this folder, deleting the files already present, before it generated and published it results. ...

I wrote recently about Creating Hyper-V hosted Azure DevOps Private Agents based on the same VM images as used by Microsoft for their Hosted Agent. As discussed in that post, using this model you will recreate your build agent VMs on a regular basis, as opposed to patching them. When I came to do this recently I found that the Packer image generation was failing with errors related to accessing packages. ...

I am really pleased to say that we at Black Marble are again hosting a venue for this year’s edition of the Global DevOps Bootcamp on Saturday May 30th 2020. For those who have not been to a previous GDBC event at Black Marble, or any of the other 70+ venues across the work, what can you expect on the day? A video keynote from an Industry Leader in the DevOps field A local keynote developing the topics of the bootcamp The remainder of the day is made up of team based hands on exercises. Lat years content can be seen here, this years will be all new. ...

Visual Studio Online is back. Unlike the previous usage of this name, which was an incarnation of what is now Azure DevOps Services, this is actually an editor for code. Just like you might expect it to be! The new VSO, which is currently in preview, is a service running in Azure that allows you to in effect run Visual Studio Code on a Linux VM. Once you have signed into VSO with an MSA and it has created the required Resource Group and VSO Plan in your Azure subscription, you create one or more ‘environments’ that defines the size of the VM to use and which GitHub hosted repo the environment will edit. ...

Background I’ve written a good few extensions for Azure DevOps Services. Most of the early ones I wrote were written in PowerShell, but of late I have tended to use Typescript (targeting Node.JS) for the added cross-platform support. This has led me to consider if it was worth the effort to convert all my legacy extensions to support cross-platform usage? This is of course assuming the tasks the extension contains are useful on a non-Window platform. There is no point porting a Windows only tool away from PowerShell. ...

Introduction There are times when you need to run Private Azure DevOps agents as opposed to using one of the hosted ones provided by Microsoft. This could be for a variety of reasons, including needing to access resources inside your corporate network or needing to have a special hardware specification or set of software installed on the agent. If using such private agents, you really need to have an easy way to provision them. This is so that all your agents are standardised and easily re-creatable. Firstly you don’t want build agents with software on them you can’t remember installing or patching. This is just another form of the “works on one developer’s machine but not another” problem. Also if you have the means to replace the agents very regularly and reliably you can avoid the need to patch them; you can just replace them with newer VMs created off latest patched base Operating System images and software releases. ...
